You’ve nailed the subject line, added the perfect CTA, and hit "send”. But, your email ends up in spam. Why?
It’s one of the biggest pain points for email marketers, sales teams, and business owners trying to reach their audience. Let’s break down why your emails are getting flagged and how you can fix email deliverability before it hurts your engagement (and reputation).
Top Reasons Your Emails Go to Spam (and How to Fix Them)
1. You’re Sending to Bad Email Addresses
Outdated, fake, or risky emails can trigger spam filters instantly.
Fix: Use a smart email verification tool like No2Bounce to scrub your list and remove spam traps or hard bounces.
2. You're Missing Email Authentication (Big One!)
If your emails aren’t authenticated with SPF, DKIM, or DMARC, ISPs won’t trust you.
Fix: Set up all three to prove you’re a legit sender not a spammer.
3. Spammy Content or Subject Lines
Caps lock, too many exclamation marks, “free money” offers these are red flags for spam filters.
Fix: Write naturally, avoid clickbait, and focus on value-driven messaging.
4. No Unsubscribe Link or Business Info
Sending emails without an unsubscribe option or address? That’s illegal in many regions.
Fix: Always include a visible unsubscribe button and a real physical address.
5. You’re Using a Free Email Domain
Using Gmail, Yahoo, or Outlook for marketing? Spam filters hate that.
Fix: Switch to a custom domain like you@yourcompany.com to build trust.
6. Your Sender Reputation Needs Work
If you’ve had high bounce rates, spam complaints, or low engagement, your sender score drops.
Fix: Use warm-up tools, send relevant content, and verify your contacts regularly.

How Your Sending Frequency Impacts Email Deliverability
One of the lesser-known causes of poor inbox placement is irregular email frequency. Whether you're ghosting your list for weeks or spamming them daily, both extremes hurt your sender reputation.
Improve Email Deliverability:
Stick to a consistent email strategy - ideally, 1 to 2 emails per week. This frequency keeps your audience engaged and shows ISPs you're a reliable sender, which improves your email deliverability rate.
Boost Email Engagement Rates:
A steady rhythm keeps your audience engaged without overwhelming them leading to better open rates, fewer unsubscribes, and stronger overall campaign performance.
